Argument IndexController not a function, got undefined: when running karma test - angularjs

Question

Here is my test file for testing the IndexController
//modules/application/tests/spec/controllers/IndexController.js
'use strict';
(function() {
describe('Application IndexController', function() {
beforeEach(function() {
module('HtEwa');
module('HtEwa.Application');
});
var scope, IndexController;
beforeEach(inject(function($controller, $rootScope) {
scope = $rootScope.$new();
IndexController = $controller('IndexController', {
$scope: scope
});
}));
it('should expose global scope', function() {
expect(scope.global).toBeTruthy();
});
});
})();
I have seen other answers but it is not working for me. And I have the files included in my karma.conf.js is:
files:_.flatten(_.values(assets.core.js)).concat([
'modules/*/*.js',
'modules/*/*/*.js',
'modules/*/tests/spec/*/*.js'
]);
I have HtEwa and HtEwa.Application module. Under the HtEwa.Application there is IndexController.
//modules/application/controllers/IndexController.js
'use strict';
angular.module('HtEwa.Application').controller('IndexController', ['$scope', 'Global',
function($scope, Global) {
$scope.global = Global;
}
]);
I guess that my IndexController file is not included, but I have included modules/*/*/*.js in my karma.conf.js and that's where the IndexController is.Or Am I missing anything?
Edit:
And the karma --log-level debug shows that all files that are needed is served.
Here are the included files that i watched from chrome

Try doing this instead:
files:_.flatten(_.values(assets.core.js)).concat([
'modules/**/*.js'
]);
Notice the use of two *. Read the File Pattern example in the karma configuration documentation.
Wherein the examples are:
**/*.js: All files with a "js" extension in all subdirectories
**/!(jquery).js: Same as previous, but excludes "jquery.js"
**/(foo|bar).js: In all subdirectories, all "foo.js" or "bar.js" files
